If this pattern holds (high tariffs on China, low tariffs everywhere else) there will be a booming industry of pass-through "factories" that receive shipments from China and then re-sell them as having come from Vietnam or some other intermediary country.
This exact thing happens frequently at scale. When countries put export controls in place on shipments to Russia recently, they had a sudden spike in exports to a number of countries known to re-ship products into Russia.
I bought ocean fish roe from my local Euro store. “Product of Belarus” which is of course landlocked.
I thought it was highly suspicious when I noticed, like evasion of sanctions on Russia. However, food products aren’t covered by sanctions in Canada and apparently, the Belarus packaging is to make it easier to sell German fish in Russia!
I still wouldn’t want to buy food that is packaged with the intent to trick people, even if the tricksters were German. (I think Germany is a pretty trustworthy and transparent country but that doesn’t apply to every single individual there).
